I can clear this up.
Steven Sinofsky, the new Senior VP of the Windows Engineering Group, does not believe in code names. I know because I spent four years under his reign in Office where we used the following internal designations:
- Office 9 = Office 2000
- Office 10 = Office XP
- Office 11 = Office 2003
- Office 12 = Office 2007
True to form, one of Sinofsky's first mandates when he took over Windows was to kill
Vienna as a code name and replace it with
Windows 7.
Also, don't assume these numbers track major versions on a 1:1 basis. For example, the code name for the successor to Office 2007 is Office 14.
